In this study, activated carbon (AC) obtained from biomass waste materials (sunflower seed shells -SSS) was synthesized by combining chemical (H3PO4 80% wt.) and thermal activation (at 544 °C). Synthesized AC exhibited a BET surface area of 1531 m2 g−1, and pore volume of 0.98 cm3 g−1. The material exhibited various surface functional groups, such as P2O7, C-O-P and -COOH, O = C, as well as a moderate graphitization degree (ID/IG
